Would you want to live in a world without electricity? No computer. No lights. No video games. Electricity is a form of energy. People don't actually make energy. They just take one form of it and change it into another. This video tells you what... it take to make electricity and how it gets to you. This video also addresses the transfer of energy from one form to another. (11:50)[more]

In this video segment, adapted from NOVA scienceNOW, learn about the natural sound phenomenon of booming sand dunes. There are about 30 locations on Earth where sand dunes produce a low, rumbling tone. Researchers have found a few key factors that bo...oming sand dunes have in common, including sand grains that are round and uniform in size, as well as layers of sand with different water content. Under the right conditions, loose sand will avalanche, transforming potential energy into kinetic and acoustic energy and producing a booming sound. (04:14)[more]

Find out why this toy is a "wonderful piece of physics". Fun video for kids to watch, this is one of those birds that perches on the edge of a glass and puts it beak into the water and then goes back up. This action continues without any help from a ...person. The explanation is interesting. Video is of good quality. (04:45)[more]

In this interactive activity adapted from NOVA Online, learn how a typical photovoltaic cell converts solar energy into electricity. Explore the components of a photovoltaic cell, including the silicon layers, metal backing, anti-reflective coating, ...and metal conductor strips. Using animations, investigate why the silicon layers are doped with phosphorous and boron, and how an electric field is used to generate electricity from sunlight. No audio.[more]

This video makes an upbeat comparison of different projectiles used in track and field events. Calculations are made to determine the energy required to throw a javelin, a discus, and a hammer. (01:20)
